SCHOOL DESK AND SEAT.

Specification of Letter-s Patent.

Applieationfiled February 17, 1909. Serial No. 478,389.

signed f r School-rooms, and particularly to the construction of the supporting-frames. The combined desk and seat ordinarily used in school-rooms has a frame provided with legs at the sides and great difliculty is encountered in sweeping and washing the floor of a room fitted with desks and seats having supporting-frames of this description. The objection above noted may be overcome employing a supporting-frame. having a smgleupright standard, and the ob ect ofmy invention is .to construct an improved form of single upright. standard and also improvedsupporting braokets for the desk and seat adapted to be arranged on, said standard, whereby they. may besecurely held at difierent elevations, and also against rotary movement thereon; may be correctly positioned with respect to each other when placed on the standard easily and quickly; may be independently adjusted to different elevations may ave a Wide range of adjustment, yet employing a very short standard; may be correctly held with respect to eachother at all times while being adjusted; andmay beturned on the standard to provide for a re -arrangement of the desks and seats in the room without removing the standard from the floor.

My invention also has for its object to construct the desk-supporting bracket so that ample knee-room is afforded beneath the desk without impairing its efiiciency as a supportfor the desk, also to so construct the seat-supporting bracket that the seat may be moved back and forth.

Furthermore, my invention has for its object to so construct the supporting-brackets for the desk and seat that all of the ordinary forms of desks and seats now in use may be supported by them.

Figure 1 is a side elevation of a combined desk and seat having a supporting-frame embodying this invention, F ig. 2Iis a transverse section of the upright standard taken on the dotted, line 2, Fig. 1,, showing the desk-supporting bracket in plan VieW Eig 3 is a transverse section of the upright standard taken on the dotted line 3, Fig. 1, showing the chair-supportmg bracket in plan view, Fig. t is an enlarged cross-section of the standard and a portion of the desk-supporting bracket taken on the dotted line 4, Fig. 1.

a represents the single upright standard which is made cylindrical and preferably hollow for lightness. It rises from a base 5 of circular form. It may be cast with said base, or it may be connected therewith in any suitable manner. Said single upright standard serves to support the supportingbrackets for both the desk and the seat. It will be screwed or otherwise secured to the floor, and a room fitted up with them may be easily swept and washed, which is very important from a sanitary point of view.

The desk-supporting bracket comprises a pair of curved arms, 0, 0, arranged horizontally and having flat tops on which the desk is placed, a collar 0, arranged at the junction of said arms, adapted to embrace the standard a, which is arranged in a plane with the arms extended outwardly therefrom, a prop 0 arranged beneath each arm, another collar 0? adapted to embrace the standard a; Whichis arranged in a plane with the lower ends of said props c and a strut" 0* connecting the two collars together. Said supporting-arms, collars, props and strut" are .all cast in a single piece, and hence form a very substantial structure. The props are curved longitudinally to correspond to the curvature of the arms. The collar, 0 is disposed some little distance below, but directly beneath the collar 0, and, as said collars are connected together, they serve, ineffect, as a tubular cylindrical portionadapted toembrace the standard. The bracket thus formed serves as a very substantial support for the desk, its curved arms extending along the bottom of the desk, at opposite sides thereof, to the remote corners and nearly to the front edge of the bottom of the desk, thereby eflective'ly supporting it, and, by the arrangement and curvature of said arms, ample knee-room is affordedbeneaththe desk. Furthermore, by providing two collars: arranged one above the other, the bracket is very securely held in position on the-standard, and all tendency to wabble' thereon is avoided.

The desk (Z is placed on the supporting- .ar-ms, .as shown in the drawing, andwhen so disposed the collars which embrace the ing the desk to a position below the top of the standard, and also for raising it to a position above the top of the standard, thereby providing a wide range of adjustment for the desk, yet employing a very short standard.

To hold the bracket in different elevations on the standard set-screws c are provided, which extend through the collars, one or both, and engage the standard. To prevent the brackets from turning on the standard said standard is provided with a longitudinal groove 0 formed in its side, and the ends of the set-screws enter said groove and engage the standard at the bottom thereof;

yet said groove provides for the accomplishment of other and more important results, as will be described.

The seat-supporting bracket comprises a base 6 on which the seat rests, a collar 6 adapted to embrace the standard a, a prop 6 arranged beneath the base 6, and a collar a also adapted to embrace the standard a, and said base, collars and prop are: all .cast in a single piece and form a verysu'bstantial structure for supporting the 'seat. The collars are arranged one above the other and serve, in effect, asa tubular cylindrical portion embracing the standard, and they are held in position on the standard by setscrews 6 extending through them, one or both, which enter the longitudinal groove 0 in said standard and engage the standard at the bottom of said groove. The essential advantages heretofore described with respect .to the desk-supporting bracket are also applicable to the seat-supporting bracket. The base 6 of the seat-supportingbracket is preferably formed to enter a guide-way formed in a plate f secured to the under side of the seat 9, so that said seat may be moved back and forth.

By providing a longitudinal groove 0 in the standard to receive the set-screws of both the desk-supporting bracket and the seat-supporting bracket it will be seen that said brackets may be easily and correctly positioned with respect to each other when placed on the standard. V

i The desk and seat may be independently adjusted to different elevations by loosening the set-screws, then sliding the brackets on the standard, and then tightening the setscrews, and, as the ends of the set-screws when loosened are free to follow in the groove 0, the brackets may be held in correct relative positions to each other while Copies of this patent may beobtained for five cents each, by addressing the being adjusted, being heldfrom movement in other than a straightli-ne. 7 It is sometimes desirable'to re-arrange the desks: and seats in a school-room to face a difierent direction, and herein 1 have made special provision for easily accomplishing this result.

' Referring to Fig.4, the standard a is provided with several longitudinal grooves a, four being herein shown, although any other number may be employed, all made alike,

and by loosening the set-screws the supportingbrackets for the desk and seat may be turned on the standard to different angles and then easily and correctly positioned with respect to each other. When the standard is thus provided with several supporting-bracket here shown may be employed to support the ordinary desks and seats now found in school-rooms, so that a school-room may be fitted up with my improved form of single standard and supporting-brackets for the desk and seat without purchasing new desks and seats, and all the advantages incident to the employment of a single standard obtained. The standard a will be made long enough to provide for supporting the brackets at different elevations and occupies a position between the desk and seat, as shown in Fig. 1.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: V

A combined school desk and seat comprising a single round supporting standard formed with vertically extending grooves, a base supporting said standard, a vertically adjustable bracket provided with a collar fitting within said standard and adapted to support a desk in rear of the standard, a second bracket adapted to support a seat in front of the standard and including a iro collar slidably adjustable on the same, each of said collars being provided with means to frictionally engage in one of said grooves.

In testimony whereof, I have signed my name to this specification, in the presence of Witnesses: o
